PrimeNG is a collection of rich UI components for Angular. One of the features it offers is a set of icons that can be used in your application. These icons are based on the popular Font Awesome library, which provides a wide range of scalable vector icons that can be customized using CSS.
In this article, we will explore how to use PrimeNG icons in your Angular application and provide some code examples to illustrate the process.
To get started, you will need to install the PrimeNG module in your Angular project. You can do this by running the following command in your project directory:
npm install primeng
Once the installation is complete, you can import the icons module into your application. To do this, open your app.module.ts file and add the following line to the imports array:
import { IconsModule } from 'primeng/icons';
Now that the icons module is imported, you can use the icons in your templates. To do this, you will need to use the p-icon component. This component takes a single attribute, name, which is used to specify the icon you want to use. For example, to use the "search" icon, you can use the following code:
<p-icon name="fa fa-search"></p-icon>
You can also use the icons in combination with other elements, such as buttons. For example, to create a search button with an icon, you can use the following code:
<button pButton type="button" label="Search">
<span class="ui-button-icon-left fa fa-search"></span>
</button>
You can also use the icons to create a list of items, where each item has a different icon. For example:
<ul>
<li>
<p-icon name="fa fa-home"></p-icon>
Home
</li>
<li>
<p-icon name="fa fa-search"></p-icon>
Search
</li>
<li>
<p-icon name="fa fa-envelope"></p-icon>
Contact
</li>
</ul>
You can also use the icons with other PrimeNG components such as p-tabView
<p-tabView>
<p-tabPanel header="Home">
<p-icon name="fa fa-home"></p-icon>
Home Content
</p-tabPanel>
<p-tabPanel header="Search">
<p-icon name="fa fa-search"></p-icon>
Search Content
</p-tabPanel>
<p-tabPanel header="Contact">
<p-icon name="fa fa-envelope"></p-icon>
Contact Content
</p-tabPanel>
</p-tabView>
You can also use icon with p-accordionTab
<p-accordionTab header="Home">
<p-icon name="fa fa-home"></p-icon>
Home Content
</p-accordionTab>
<p-accordionTab header="Search">
<p-icon name="fa fa-search"></p-icon>
In addition to using icons in templates, you can also use them in your component classes. For example, you can use the `fa` class to add an icon to a button in a component class. To do this, you will need to import the `DomSanitizer` service from the `@angular/platform-browser` module, and use it to create a safe `fa` class.
Here is an example of a component class that uses an icon with a button:
import { Component, OnInit } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Component({
selector: 'app-example',
template: <button pButton type="button" label="Search" [ngClass]="searchIcon"></button>
})
export class ExampleComponent implements OnInit {
searchIcon;
constructor(private sanitizer: DomSanitizer) { }
ngOnInit() {
this.searchIcon = this.sanitizer.bypassSecurityTrustHtml('fa fa-search');
}
}
You can also use the icons in combination with other PrimeNG components, such as the `p-tree` component. The `p-tree` component allows you to create a hierarchical tree structure, where each node can have an associated icon. Here is an example of how to use icons with the `p-tree` component:
<p-tree [value]="nodes" [loading]="loading">
In this example, the `p-icon` component is used inside the `ng-template` element to create an icon for each node in the tree. The `name` attribute is set to "fa fa-folder" to use the folder icon.
Another example of using icons is with `p-dataTable` component. You can use `p-icon` component inside a `p-column` element to show icons in the data table. Here is an example of how to use icons with the `p-dataTable` component:
<p-dataTable [value]="data" [responsive]="true">
<p-icon name="fa fa-edit" (click)="edit(row)">
<p-icon name="fa fa-trash-alt" (click)="delete(row)">
In this example, we are using `p-icon` component inside the p-column element, to show edit and delete icons.
PrimeNG icons are a powerful tool for adding visual appeal and functionality to your Angular application. With the wide range of icons available and the ability to customize them using CSS, you can create professional-looking and user-friendly applications. The above examples should give you a good starting point for
